When using high contrast settings in firefox (preferences->content->colours set white-on-black and always) the status of jobs is invisible since it is shown only using colours. It can be worked-around using the Stylish add-on adding an :after pseudo-element to each colour button with a content property to add a tick, a cross or other symbol. But maybe there's an even better idea, particularly to draw one's eye to particular statuses the way colours do.
Oh I had an idea. This could be much easier to scan if it the results were aligned in some way: Test name: result Test naem: result Etc, the most obvious is a table. Colours and symbols could be used together in the table layout, a special "vision impaired mode" won't be necessary and I believe it'll be more readable for everyone. Thanks.
